GHAINIBINDER.

SPECIFICATION forming part of Letters Patent No. 398,382, dated February26, 1889.

Application filed January 29, 1837. Serial No. 225,835. (No model.)Patented in England December 6, 1887, No. 16,741.

To all whom t may concern:

Be it known that I, HENRY F. CRANDALL,

Grain-Binc'pers; and I do hereby declare thatl the following is a full,clear, and exact description thereof.

My invention relates to grain-binders, and is designed as an improvementon the device for Which Letters Patent No. 339,142 were granted toJoseph P. Bullock on the 6th day of' April, 1336. Its nature will befully set forth hereinafter.

In the drawings, Figurel is a vertical crosssection of the binder withthe knotter re moved, showing the position of the compressing mechanismbefore a gavel of grain has been accumulated on the compressing-1ingers. Fig. E2 is a detail section showing the eempressing mechanism inoperation. a rear elevation ot' the compressor-sprin g and framethereof. Fig. 4. is aseetion ofthe same on line :r a', Iig. l; and Fig.5 is a detail.

A is the needle-shaft, and B the needle, which is keyed to theneedle-shaft, as usual, and C a bell-erank, that is slipped loosely uponshaft A andlies close up against the needle. The bell-crank has a lug,c, on its upper arm, through which a set-bolt, o', is screwed inposition to be on a line with theloweredge of the needle, and the lowerarm of bell-crank C has ngers C adjustably secured to it by two bolts,one bolt, d, (imlieated by dotted lines,) passing through one of aseries of holes, d', and the other, d2, through a slot, d3, in thebell-crank. The hub of the needle on its end opposite the belleerank Cis provided with a stop, It, for a purpose hereinafter to be explained.

D is a spring-frame, that ishuug to the gaspipe E beneath. the needle bymeans of a casting, D', to which. it Ais hinged, and which also securesone end of a spring, IP, to the gas-pipe, and is in turn secured theretoby a bolt-,fl This casting D has top and bottom fingers, g g',respectively, to limit the swing of the frame D.

G is a plate that is adapted to slide in the Fig. 3 is frame D, and theshank 7L of a catch, H, is

passed down through the top of the frame and through a spiral spring,lll, and then fastened to the plate G, so as to confine the springbetween the plate and Jthe upper part of the frame.

K is a finger that pivoted to the upper g portion of the frame D at oneend, while its other end lies upon the hub of the needle, and is offsetat a for engagement with the lug or stop a on the heel of the needle.

Near its rear end the finger is cast or other- Wise provided on itsunder side with a hook, by which the finger is attached to the outer endof spring F, which latter not only serves to hold the finger down on thehub, but also serves to draw the upper end of frame D toward the needleshaft Instead of being straight, as in the patent to Bullockhereinbefore referred to, the frame D is made with a bend, D2, whichguides the lower end ofthe shank of catch H, so as to eause said catehto rise in the arc described by the engaging end of the bell-crank as itlifts the catch; otherwise the catch would travel at a tangent to thisare, (which are is shown in dotted lines, Fig. 2,) and the bell-crankwould be liable to disengage prematurely.

The operation of my device is as follows: \Vhen a sufficient amount ofgrain has been packed upon the trip-fingers to cause them to trip themachine into gear, by pressing down the front arm of bell-crank Cuntilthe bolt e by its pressure on the needle slightly lifts it theextreme upper end of the bell-crank engages with the catch H, and thecatch takes the Weight of the grain as Well as the strain caused by thepressure of the needle upon the gavel as the latter is encircled, andremains in engagement with the bell-crank until the needle, as it beginsto return, Carries the lug shorten or lengthen the action oi' thecompressor-Hugers it is only necessary to tn rn the bolt c in or out.

Having thus fully described my invention, what I claim as new, anddesire io seenreliy Letters Patent, i sh l. In a grain-binder, thecombination, with the compressi11g-fingers and the bell-crank to whichthey are hung, of a spring-catch for engaging the inner end of thebell-crank, and a frame in which the shank of said springcatcli slides,said frame being prevented from vibrating extensively by stops coactingwith stops on the main frame, havinga bendwhich, acting on the lower endof the shank of the spring-Catch, serves to tilt the Catch and permitsit to maintain its engagement with the bell-crank as it is drawn up bythe action of the pressure of the gavel on the compressingfingers, asset forth.

frame, said frame'being kept from extensive vilo ration by suitablestops, but haviugcurved guides for the catch, so that the end of thelatter may travel in the arc of acircle in spite f of the restrictiveaction oi' the stops, substan tially as and for the purpose set forth.

3. 1n a grain-binder, a bracket secured to a supporting-bar of themachine and provided with an upper and lower stop, aframe pivoted to thebracket, a spring-catch mounted in the frame to engage thecompressor-fingers, and means, substantially as desoribechforactuatingsaid frame at predetermined intervals, as set forth. l

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisf cousin, in thepresence of two witnesses.
